We own a 2018 HR-V EX 2WD we bought new in January 2018. It has 70k miles. We have had all regular service done on it as scheduled.
These problems we began having around February 2022. Sometimes (not always) when the car is parked- no key fob anywhere near it- the dash lights and relays start clicking and blinking in random patterns. If the car is locked, the alarm will usually start going off when this happens. Also if the lights switch was set to Automatic, they sometimes come on and drain the battery if we don't see it happening. The car is drivable- when on and driving everything seems to behave normally.
For now, the car remains in our garage with the battery disconnected. Luckily we have other ways of getting around.
1. Taken it to a Honda dealer (the one we purchased it from) and had them look at it while we were getting the start button replaced under warranty. They said the codes said something about the dash mounted sunlight sensor not connecting with the Gauge Control Module (the whole dash unit containing the gauges and odometer). So they replaced the sensor. It didn't stop the problem.
2. We had the battery replaced with a brand new one. It did not stop the problem.
3. We had our Honda trained mechanics (not the dealer) replace the Gauge Control Module. It didn't stop the problem.
4. Next we had our mechanics replace the under dash Fuse Box Assembly which controls all of the wiring harnesses. It didn't stop the problem.
Our mechanics are stumped- we have used them for more than 10 years and we really respect them. They suggested we write American Honda directly, and we have done so by email about 1 week ago. I have heard back from them and now have a Case number but have heard nothing else.
I do have one other thing for you all to see- a video of this actually happening. I will place the link to my Dropbox so you can see it. All the noises you hear and lights you see are from the HR-V itself- I am just sitting in the seat. We really hope this can be fixed. We have really enjoyed the car otherwise.
Here's the link to the video. Any ideas on how to fix this are greatly appreciated.
